ELECTRICITY AND POWER DEFINITION

Efficiency (Generated)%
Total energy generated (kWh) * 3600 * 100 divided by:
Quantity fuel (kg) * higher heating value of fuel consumed (kJ/kg)
Efficiency (gen) is related to Heat Rate (gen) by:
Efficiency (gen) (%) = 3600 * 100 .
Heat Rate (gen) (kJ/kWh)

Efficiency (Sent Out)%
(Total energy generated (kWh) - total auxiliary energy (kWh) * 3600 * 100 divided by / Quantity fuel (kg) * higher heating value of fuel consumed (kJ/kg)
Efficiency (s/o) is related to Heat Rate (s/o) by:
Efficiency (s/o) (%) = 3600 * 100 / Heat Rate (s/o) (kJ/kWh)

Electrical efficiency (Cogen) NFT)
[Cogen gross elec output] + [imported electricity] - [parasitic electricity] dividede by:
[Fuel to cogen unit] + [fuel used for imported electricity]

Embedded Generation
Smaller-scale generators that are connected to electricity distribution networks. By nature of where they connect to the grid, they are distributed generators. Are in contrast to large-scale coal-fired generators that are connected to very high voltage electricity transmission networks.

Enthalpy
Measure of the heat content of a substance.

Entropy
A measure of unavailable energy in a thermodynamic system.
